[PATCH] non-integrated local APIC LVTT init compatibility

Add back the old i82489DX bits to use timer scaling for the old
non-integrated APIC setup. 

It's possible these bits don't need to be set on i82489DXs,
but not having this HW for testing I elected to maintain
the old behaviour on these old machines.
